LWQQGL llyVENTOR. J 17 f 0 Can/70f By- W ating in said housing, a springmechanism side of the spring seat. Between the spring' ingthrough perforations 43, 43 at either seat. 42 and the saddle 38 is mounted the spring mechanism 20. Said spring mechanism preferably Consists of an outer spring 14: and an inner spring 45* nested therein.

In normal position of the parts of the draft rigging, as'illustrated in Figs. 1 and 2 of the drawings, the followers engage the stop shoulders, and'the friction blocks are substantially within the housing and adjacent each other. On rearward movementof the draW bar the wedge. is forced rearwardly by the front follower, the rear follower is stationary against the rear stop shoulders, and as the wedge 22 travels rearwardly within the housing 21 the friction blocks 23, 23 are forced upwardly and downwardly respectively, and away from each other, in sliding frictional action with the wedge, rear follower and'housing. The engagement of the outer friction face26 of each friction block with a friction face of the housing spring seat, the saddle enga forces the .housing' forwardly, the spring bolts are thereby drawn forwardly, pulling the spring seat 42 toward the rear follower 18-, and com resslng the spring mechanism '20 between t e spring seat 42 and the sad-" die 38, which is stationary against the rear follower. This action in buffing movement of the gear continues until the we'dges rear face 34'engages the rear follower, and the" parts are in the position illustrated in Fig.

3 of the drawings. On pulling'movement' of the draw-bar the front follower 17 is stationary against the front stop shoulders,-

and" the wedge 22 is stationary against said follower, the yoke 15 draws the rear follower 18 'forwafdly, thus forcing the fric- 40.

tion'blocks away from each other, the said friction blocks in their separating movement being in frictional engagement with the rear follower, the wedge and housing, and forcing the housing forwardly in its relation to the forwardly traveling rear follower. Meanwhile the spring mechanism is being compressed between the saddle 38 and the spring seat 42 by the traction of" being'mounted between the saddle and the ging the rear follower, the spring seat being connected to the housing by the spi-ing'bolts, and the friction blocks operating to forwardly compress the springs on both forward and rearward moveinent of the draw-bar.
